Protein shields for dehydration
Turning motor into anchor A motor in the fl y oocyte is turned into a static anchor to hold its polarity-inducing cargo in place, say Renald Delanoue, Bram Herpers, Jan Soetaert, Ilan Davis (University of Oxford, UK), and Catherine Rabouille (University Medical Centre Utrecht, Netherlands). The switch from motor to anchor is thrown by an RNA-binding protein called Squid. Squid mutants were orig...
متن کاملFace shields for infection control: A review.
Face shields are personal protective equipment devices that are used by many workers (e.g., medical, dental, veterinary) for protection of the facial area and associated mucous membranes (eyes, nose, mouth) from splashes, sprays, and spatter of body fluids. Face shields are generally not used alone, but in conjunction with other protective equipment and are therefore classified as adjunctive pe...
متن کاملSelective functionalization: Shields for small molecules.
P rotecting groups have a long history in synthetic chemistry 1. A protecting group is covalently attached to one functional group to block its reactivity while a second functional group undergoes a chemical transformation, after which the protecting group is then removed (Fig. 1a). The use of protecting groups requires both protection and deprotection steps, so efficiency considerations dictat...
متن کاملCollagen corneal shields.
Collagen corneal shields were developed as a corneal bandage lens and are currently indicated for ocular surface protection following surgery and in traumatic and nontraumatic corneal conditions. Collagen shields are manufactured from porcine or bovine collagen and three different collagen shields are currently available with dissolution times of 12, 24, and 72 hours. The theoretical, experimen...
متن کاملHow Concentration Shields Against Distraction
In this article, we outline our view of how concentration shields against distraction. We argue that higher levels of concentration make people less susceptible to distraction for two reasons. One reason is that the undesired processing of the background environment is reduced. For example, when people play a difficult video game, as opposed to an easy game, they are less likely to notice what ...
